President Obama to appear on 'Letterman' for the last time Monday

President Barack Obama is to make his eighth and final visit to the Late Show with David Letterman Monday, CBS announced.

This will be Obama's third appearance as commander-in-chief. He last appeared on the broadcast Sept. 18, 2012, and prior to that on Sept. 21, 2009. As an Illinois senator, he appeared on the Late Show five times, beginning in 2004 and continuing through his 2008 presidential campaign.

First lady Michelle Obama was a guest on Thursday's show.

As previously announced, Letterman will retire as host of Late Show on May 20. Stephen Colbert will then take over.
